College athletics in the United States or college sports in the United States refers primarily to sports and athletic training and competition organized and funded by institutions of tertiary education (universities and colleges) in a two-tiered system.

The first tier includes the sports that are sanctioned by one of the collegiate sports governing bodies. The major sanctioning organizations include the National Collegiate Athletic Association (NCAA), the National Association of Intercollegiate Athletics (NAIA) and the National Junior College Athletic Association (NJCAA). Individual sports not governed by umbrella organizations like the NCAA, NAIA, and NJCAA are overseen by their own organizations, such as the Inter-Collegiate Sailing Association, National Collegiate Boxing Association, USA Rugby, American College Cricket, National Collegiate Roller Hockey Association and Intercollegiate Rowing Association. Additionally, the first tier is characterized by selective participation since only the elite programs in their sport are able to participate; some colleges offer athletic scholarships to intercollegiate sports competitors. The second tier includes all intramural and recreational sports clubs, which are available to a larger portion of the student body. Competition between student clubs from different colleges, not organized by and therefore not representing the institutions or their faculties, may also be called "intercollegiate" athletics or simply college sports.
